Abstract
The invention relates to a 5-amino-4-hydroxy-7-benzyl-8-methylnonanamide derivative, a preparation method thereof and application thereof in medicines. Specifically, the invention relates to a novel 5-amino-4-hydroxy-7-benzyl-8-methylnonanamide derivative shown in a general formula (I) in the specification, a preparation method thereof, and medicinal composition containing the derivative as well as application of the medicinal composition as a therapeutical agent, particularly as a Renin inhibitor and medicaments for treating and resisting high blood pressure and diseases related to Renin activities, wherein all substituent groups in the general formula (1) are identical to those defined in the specification.
Description
Technical field
The pharmaceutical composition that the present invention relates to a kind of new 5-amino-4-hydroxy-7-benzyl-8-methyl pelargonamide analog derivative, its preparation method and contain this derivative with and as therapeutical agent particularly as renin inhibitor with as the purposes with the medicine of renin activity diseases related such as hypertension.
Background technology
Aspartate protease (Aspartic Proteinase) is a class important protein lytic enzyme, participates in the metabolism and the biological regulating and controlling effect of body.In general, their active centre is made up of the catalytic asparagicacid residue of two high conservatives.Common aspartate protease comprises: stomach en-, feritin (Renin), beta-secretase (beta-amyloyd precursor protein lyase, β-site amyloid precursor protein cleaving enzyme, BACE), hiv protease, human T-leukemia virus's proteolytic enzyme etc.Their its generations with numerous disease are relevant, as: in the essential hypertension people, because the katalysis of feritin makes the angiotensin I level raise; Generally believe at present that in addition one of alzheimer's disease main pathogenesis is to form owing to abnormal deposition that BACE acts on the product amyloid beta behind the amyloid precursor protein.In addition, human immunodeficiency virus and human T-leukemia virus all need the participation of aspartate protease separately in its ripening process.
Feritin (Renin), claim Angiotensinogenase again, it is synthetic and release by renal glomerulus, in blood, proangiotensin is cracked into decapeptide angiotensin I (angiotensin I subsequently, Ang I), at angiotensin-converting enzyme (angiotensin converting enzyme, ACE) under the effect, AngI is cracked into octapeptide Angiotensin II (angiotensin II, Ang II), the AngII of high biological activity can shrink direct rising blood pressure by arteries, also can discharge the aldosterone blood pressure that raises indirectly by regulating suprarenal gland.This begins to the regulation mechanism that generates till the aldosterone from feritin, be called renin-angiotensin-aldosterone system (Renin-angiotension-aldosterone system, RAAS).
Renin-angiotensin-aldosterone system (RAAS) is keying action target spot (the Nature Reviews Drug Discovery 2002 such as Zaman M.A. of pharmacological agent cardiovascular system diseases; 1:621-36), the generation and the blocking-up angiotensin-ii receptor of the secretion that it can be by suppressing feritin, activity, prevention Angiotensin II are realized.At present, the blocker of angiotensin-convertion enzyme inhibitor (ACEi) and angiotensin receptor (Angiotensin AT1 receptor blockers, ARBS) all go on the market, some medicine becomes antihypertensive a line medicine (Su Dingfeng etc., Chinese Journal of New Drugs and Clinical Remedies 2001; 20 (2) 139-42).But also there are some problems in current ACEi inhibitor and ABRs, not exclusively block as the non-specific RAAS of the causing system of ACEi, cross high side effect thereby produce as dry cough, headache, blood potassium.Because feritin is directly regulated the initial link in the RAAS system---AngI generates, and vasotonia have high degree of specificity for endogenous, is the research focus that acts on the RASS medicine therefore always.
In addition, by suppressing feritin blocking-up RASS except energy is hypotensive, can also reduce trouble diabetes and other cardiovascular disease risk of causing because of hypertension.As block RAAS and can be used for treating liver, renal fibrosis (Contrib Nephrol.2001 such as Gaedeke J; 135:153-60, World JGastroenterol.2009 such as Regina M.P.; 15 (21): 2579-86), atherosclerosis, myocardial hypertrophy, myocardial fibrosis, diastolic dysfunction, diabetic complication diseases such as (as ephrosis, eye diseases).
First-generation renin inhibitor is a peptide class substrate analogue, and the body internal stability is poor, and action time is short, can only the enteron aisle external administration (people J Biol Chem such as Cumin F, 1985; 260 (16): 9154-57.).After this carry out chemically modified on its basis, synthesized the oral plan peptide of s-generation class renin inhibitor, as CGP-29287, CGP-38560, Rui Mijilun (Remikiren, Ro425892), Yi Najilun (Enalkiren, A64662) (WoodJ M etc., Hypertension, 1985; 7,797-803; Expert Opin Ther Patents2003 such as Maibaum J; 13,589-603; Wood J M etc., J Cardiovasc Pharmacol 1989; 14,221-26).But in the experimentation on animals, its oral administration biaavailability extreme difference (<2%), the transformation period is short, greatly limits its antihypertensive activity performance, thereby can't be applied to clinical.In recent years, along with the development of medicament research and development technology, design the non-peptide micromolecular of third generation renin inhibitor.Disclosed relevant patent has: WO8805049, EP0678503, WO2004002483, WO2004002957, WO2005051895, WO2005070871, WO2006069788, WO2006103277, WO2007031557 etc.Wherein, the renin inhibitor of having developed at present, because molecular weight is bigger, human bioavailability is low, therefore, improves actively, improves pharmacokinetic property and be the main direction of studying of renin inhibitor from now on.
Purpose of the present invention is exactly to keep the better active while of inhibitor, and the medicine that improves compound is for character, and a kind of clinical medicine that feritin suppresses active and can be used for hypertension etc. and the treatment or the alleviation of renin activity diseases related that has is provided.
